COMBINED ADVERTISING AND PRICE DISPLAY BOARD Filed April 7, 1950 l) gm/m/ MVM abba/MM@ Patented May 3, 1932 UNITED STATES PATENT OFFICECOMBINED ADVERTISING AND PRICE DISPLAY BOARD Application med Aprii 7,1930. serial No. 442,228.

This invention relates to improvements ink combined boards.

It is the object of the invention to provide a novel and improvedcombination board having means adjustable to indicate various multiplesof the price of a commodity such as gasoline, throughout any ordinaryrange of fluctuation of the unit price thereof, while conveniently andsimply providing for an advertisingdisplay upon an interchangeable paneThe invention has to do particularly with the mechanical constructionand simplification of the parts comprising `the complete apparatus.

In the drawings:

Figure 1 is a front elevation of equipment embodying this invention. Y

Figure 2 is an enlarged detail view thereof in a section taken generallyin the plane indicated at 2 2 in Fig. 1.

Figure 3 is an enlarged detail view of the structure shown in Fig. 1 asit appears in section taken in the plane indicated at 3 3 in Fio. 1.

Eike parts are identified by the same reference characters throughoutthe several views.

A basic frame work yupon which the structure is assembled comprises apair of vertically extending sheet metal channels 5 and 6 united attheir tops by an angle iron 7 and at their bottoms by a bar 8. The frontmargins of the respective channels are flanged inwardly at 9 andoutwardly at 10. Each channel has a face plate 11 which is bent backupon itself at 12 about the flange 10 and is welded or riveted thereto.Each face plate is also welded or riveted to iange 9 advertising andprice display through an intervening plate 13 having a retaining portion14 which co-operates with the retaining member 15 to hold a sheet ofglass 16 in place before an opening 17 in the face plate 11.

The spacing plates 13 hold the face plates 11 suiiiciently far from theflanges 9 of the respective channels to provide guideways in which themargins of a sheet m-etal panel 2O are slidably receivable. The frictionbeface of member 21 tween this panel and the members forming itsguideway is considerable, but'the panel may be withdrawn when desiredfor the substitution of another panel. Thus advertising matter may bepainted or printed upon the panels in advance and mountedon the displayequipment through the simple eX- pedient of changing panels.

The device may, if desired, be provided with an additional displaysurface upon the panel 21 which is held in place by four bolts, thosedesignated at22 passing through the as shown in Figs. 1 and 3, and thoseshown at 23 passing through the angle iron 7 and the sheet metal bracket24 65 which are welded to panel 21 and serve as covers for thechannel-shaped housings 5 and 6.

Upon the face plate 11 is a series of digits representing multiples ofthe units of commodity to be sold. For example, the digits 1 to 20appearing in Fig. 1 may represent gallons ofgasoline. Guided by upperand lower supports 25 and 26 within the channelshaped housings 5 and 6respectively, are rolls 75 28 upon which is wound a chart 29, the chartextending across the opening 17 in face plates 11 protected by the glass16. This chart bears columns of figures such as those shown in Fig.

1, the figure at the top of the chart representing the unit price of thecommodity and the remaining figures of the column representing theprices at which multiples are sold. It will be noted that the price ofthe multiple is not necessarily a multiple of the unit price. On thecontrary, the multiple is preferably such as to amount to a full coininstead of a fraction thereof. Each of rolls 28 has a spindle extensionsuch as that shown at 30 in Fig. 2, which is accessible through 90 thebottoms of the respective housings for manipulation, whereby the rollsmay be turned to present new columns of figures through the windows 17in the respective housings in accordance with fluctuations in unitprices.

I claim:

1. A device of the character described, comprising spaced uprightchannels hanged at their respective margins, means connecting saidchannels to comprise a frame, cover plates for the respective channelsspaced from marginal portions of said flanges to provide guideways atthe sides of the channels, and a removable panel receivable in saidguide- Ways.

2. A device of thecharacter described, comprising spaced channels havingfront marginal ilanges, frame members connecting the rear portions ofthe channels, apertured face plates for the channels having marginsspaced Jfrom the margins of the channel flanges, intervening spacerplates, a panel slidable in the guideways deiined by the channelflanges, the spacer plates, and the margins of the face plates.

3. A device of the character described, comprising spaced channelshaving front Inar, ginal flanges, frame members connecting the rearportions of the channels, apertured face plates for the channels havingmargins spaced from the margins of the channel flanges, interveningspacer plates, a panel slidable in the guideWays delined by the channelflanges, the spacer plates, and the margins of the face plates, andglasses covering the apertures in the face plates and engaged by thespacer plates.

4L. A display device comprising spaced housings, frame membersconnecting said housings, brackets constituting closures 'for the topsof said housings, and a panel carried by said brackets, said housingsbeing windowed and provided internally with display mechanismscomprising rollers for manual manipulation, and a chart Wound thereonand provided with columns of display ma terial adapted to be registeredWith the openings in the respective housings.
